A civilian defense contractor accused of giving military secrets to a Chinese girlfriend half his age will be entering a guilty plea.

His attorney Birney Bervar said Tuesday Bishop is expected to plead guilty to one count of transmitting national defense information to a person not entitled to receive it and one count of unlawfully retaining national defense documents and plans.

Bishop was arrested last March at the headquarters for the U.S. Pacific Command, where he worked.

An FBI affidavit last year alleged the then-59-year-old gave his 27-year-old girlfriend classified information about war plans, nuclear weapons, missile defenses and other topics.

Bervar has said the two were in love and that the case was about love, not espionage.
